This constriction increases velocity and energy transfer resulting in the projectile traveling a shorter distance per shot. The Octagonal shape defies cross sectional area changes that can occur between flush mount chokes and choke tubes with a longer parallel section. This reduces the possibility of the fouling that can occur when the choke tube is cold. The Octagonal shape also allows for easy choke tube removal while guaranteeing concentricity with the bore.
